MACHINE FOR PACKING TOBACCO IN BAGS.

EI'ECIFJICATION orming part of Letters Patent No. 341,457. dated May 11, 1886. Application filed July 29, 1885. Serial No. 172,941. (No model.)

To all whom, it may concern.-

Be it known that I, HENRY R. CORKHILL, of Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in Machines for Packing Tobacco in Bags, which improvement is fully set forth in the following specification, and shown in the accompanying drawings.

The object of my invention is to produce an improved-machine for packing tobacco or other similar substances in cloth or other bags, by means of which much time is saved in the operation and the packing thoroughly done, the invention being fully described in the following specification, and more particularly pointed out in the claims.

Referring to the drawings, Figure 1, Sheet 1, is a front elevation of the tobacco-packing machine, showing all parts in place as when in use, parts being shown in different positions by full and dotted lines, some minor portions being broken away and vertically sectioned; Fig. we view of the same, taken as indicated by arrow as in Fig. 1, most of the nearer post or upright of the frame being broken away to better show the working parts of the machine, the table and parts of the frame being vertically sectioned as upon the dotted line 31 in Fig. 1; Fig. 3, Sheet 2, a view from in front of a part of the frame with one of the li fters for the funnel and parts attached, and the sliding head and parts combined therewith, the sliding head beingin part centrally and vertically sectioned, parts not necessary to-the figure being broken away and omitted; Fig. 4, a front elevation of parts at the upper right-hand corner of the machine, a part of the clutch-collar and hub of the band-wheel being vertically sectioned to uncover contained parts, a portion of the face of the band-wheel being broken out; Fig. 5, a view of some of the parts shown in Fig. 3, viewed as indicated by arrow in said latter figure, the upright or post and sliding rod being sectioned as on the dotted line 2, drawn to further show the relation of the parts; Fig. 6, a view of the clutchcollar, seen as indicated by arrow as in Fig. 4, drawn to better show the relation of the cl utch-bar to the other adjacent parts, the hub of the band-wheel and other parts being shown in dotted lines, apart of the face of the clutch-collar being broken away to uncover the downward-projecting arm of the clutch-bar; Fig. 7, a view of a portion of the table, seen as indicated by arrow 5 y in Fig. 1, drawn to show the manner of setting the lower end of the funnel, the upright and sliding rod, with the funnel, being horizontally sectioned as upon the dotted line 2 in Fig. 1; Fig. 8, a view of a portion of the clutch-collar, with the clutch-bar and other parts, seen from the same direction in which Fig. 4is seen, the clutch-collar and other parts being vertically sectioned as upon the dotted line no in Fig. 6, drawn to show more fully the clutch-bar and the manner of operating it; Fig. 9, a plan view of the treadle of the machine, with other combined parts, the standard and treadle-rod being transversely sectioned as upon the dotted line y in Fig. 1, and viewed as indicated by the arrow pointed thereon, drawn to more fully show the form of the parts; 10, a view of the head of the clutch-shifter, seen as in Fig. 4, drawn to a scale double the size to showanore fully the 7 retaining-pin for the arm of the clutch-bar, a part of the head of the.clutch-shifter being vertically sectioned; Fig. 11, an elevation of the head of the clutch-shifter, viewed as indicated by arrow z in Fig. 4-, drawn to further show the relation of the retaining-pin to the arm of the clutch -bar; Fig. 12, Sheet 1,a view of the funnel with a bag drawn over the same, ready to receive the tobacco; Fig. 13, a view of one of the liftinghooks with some of the parts operating therewith, drawn to show the spring-pin for aiding to control the movements of the hook, it part of the shaft or holder 0 being vertically sectioned; and Fig. 14, a plan of the rest for the funnel, showing the former in different positions of adjustment by full and dotted lines, the various figures being drawn to different scales for the purpose of showing the difterent parts to better advantage.

The tobacco to be pressed is placed in a funnel (made for the purpose, having a long parallel tubular part or barrel) in a measured quantity, and forced into a bag by means of a plunger carried down within the funnel, the [o0 bag being first drawn, as a sheath, over the small end of the funnel, which is made long through openings 0 in the table.

and cylindrical for the purpose, as shown in the drawings.

Referring to the parts, A is the frame of the machine, B B the standards or posts thereof, 0 the table, and D strong cross-bars uniting the standards and supporting some of the essential parts of the machine. At the top of the frame two shafts, f g, are mounted in bear lugs S T in a horizontal line, the shaftf being provided with a crank, K, at its inner end, and the shaft 9 provided at its inner end with an opposing shorter crank, L, the pins a c (which lap by each other) of the respective cranks being joined by a rigid link, 1), parallel with the faces of the cranks. The outer end of the shaft f is provided with a beltpulley, F, fitted to turn loosely thereon, and a clutchcollar, A, keyed rigidly thereto, which collar and shaft are at intervals turned by the pulley by means described further on.

Guides or rests B G, secured opposite each other upon the inner faces of the posts B B of the machine, serve to hold parallel vertical sliding rods G G, the lower ends of which rods rest in bearings d d in the table. A crosshead, h, connects the sliding rods below the guides, being joined rigidly to each, and a connecting-rod or pitman, H, connects the middle point of said cross-head with the pin a of the long crank K. By means of this connection of parts, when the crank makes a complete revolution the rods G G are carried downward and upward through their bearings, as indicated by dotted lines, passing A grooved guide, It, is secured vertically to the cross-bars D, midway between the parts of the frame, a sliding head, D, being fitted to slide vertically therein. This sliding head is connected by means of a rod or pitman, I, to the pin 0 of a short crank, L, by means of which, when the crank is turned through a complete revolution the sliding head will be carried downward and upward along the guide is, as indicated. Now, as the cranks are rigidly connected by the link 6 the axes of their respective pins and shafts being in the same plane, and the cranks of different length, it will be understood that when the latter are rotated the rods G G and sliding head D will move simultaneously and always in the same direction, but at different rates of speed, the rods moving the more rapidly, but the sliding head with great power. The sliding head is made hollow at its upper end to receive the lower end of the pitman I, the latter being held by a cross-pin, e, and bored out at its lower end to receive the shank of the plunger 0, which plunger is preferably made of hard wood and of circular, oval, or other form in cross-section, according to the form of the tobacco packages to be filled. Vhen thus held in the sliding head, the axis of the plunger is vertical, and the funnel charged with tobacco is held vertically by an operator upon the table under the plunger, as shown, the descent ofl which plunger by the revolving crank presses the tobacco into a compact mass within the lower end of the funnel.

e e are two similar blocks, held adj ustably upon the rods G G by means of set-screws, each of which supports a horizontal shaft, 0, having their axes directed toward the center line of the machine, said shafts being each provided at their opposing ends with pivoted hookpieces a, which together constitute lifters for the funnel. These hooks swing freely in a vertical plane, and are held in position by the blocks Z, to catch under the bead or flange r of the funnel, as shown in dotted lines in Fig. 1, when the rods G G are carried to their lowest position by the action of the long crank. The shafts o 0 are fitted to, slide laterally through or within the blocks Z, to bring the hooks or lifting-arms n nearer together or farther apart, to adapt them to seize funnels of different sizes or diameters, the shafts being held in positions of adjustment by setscrews 12 The plunger is made of such length that when down the distance between its lower end and the table, corresponds to the length of the tobacco package, the tobacco being pressed within the funnel between the end of the plunger and the surface of the table.

As above stated, the bag for receiving the tobacco is drawn over the end of the funnel, and after the descent of the plunger, and while the cranks are moving upward, the funnel is moved more rapidly than the plunger, and drawn over the latter, causing the same, during its upward movement, to force the block of pressed tobacco out of the funnel into the bag, which latter is at the same time pushed off of the funnel. As the rods G G near their upper position, the upper curved ends of the hooks come in contact with the rigid deflectors a 17, by means of which the lower ends of the hooks are spread and release the funnel, which is seized by the operator, drawn off the plunger and laid aside to be refilled. These deflecting-fingers i are held by supports 1), secured to a cross-bar, D, said deflectors being adjustable, as shown in Fig. 3, for the purpose of causing the lifters to properly release the funnel. The blocks Z are also fitted adjustably upon the rods G G, so they may be moved upward or downward when used with funnels of" different lengths. The band-pulley F is turned by a belt in the usual manner, and is fitted to turn the cranks, when desired, by the operator, who causes a sliding bolt to be thrown out of the clutch-collar A to engage a projection of the wheel. The machine as constructed, when left to itself, will stop automatically after a complete revolution of the cranks,when the latter stand straight upward, as shown in Figs. 1 and 2, and will start again only when the operator allows the clutch-bolt to slide out to encounter a projection of the hub of the wheel. This is done when another funnel is filled and presented to the plunger. as shown. The projections s of the wheel are preferably pieces of steel set into enlarged parts of the hub, there being, by preference, two in number diametrically opposite each other. The clutch-bolt a is fitted to slide horizontally in a cavity in the clutch-collar, it being at the same distance from the center of the shaft that the projections s are. The inner end of the clutch-bolt a is bored out, as shown in Fig. 8, and a coiled spring, f, inserted therein, which presses againsta plate, k, secured to the clutch-collar A, by means of which spring said clutch-bar a is pushed partially out of the clutch-collar and made to engage a projection, s, of the wheel F, the outer ends of said projections passing close to the face of the collar as the pulley rotates. An arm, a, of the clutch-bar projects downward through a slot, 9, in the substance of the collar sufficiently far to glide along the surface of an adjacent inclined head or throw out, (1, which latter is placed in posit-ion to act upon the arm and withdraw the clutch-bar within the clutch-collar against the action of the springf, thus disengaging the collar and pulley and stopping the operation of the machine. The clutch collar is secured to the shaft relative with the crank in such position that the arm of the clutch-bar will encounter the throw-out d, withdraw the clutch-bar, and stop the machine when the cranks are up.

0 is a small catch-bolt resting in a cavityin the clutch-collar parallel with the clutclrbar, which is held by a spring in position to have its outer beveled end project from the face of the clutch-collar sufficiently to be encountered by the revolving projections s of the pulley. The projecting end of this catch-bolt or catch is beveled like the projecting bolt of a doorlock, and in such direction that when the projections of the wheel strike it as they move around it slides backward within the collar and allows them to pass without affecting anything? This catch-bolt is arranged with reference to the clutch-bar so that the space between them, when the latter projects from the collar, is just sufficient to receivea projection s of the bandwheel, as indicated in Fig. 6. By this means the collar and band-wheel are so locked together, when a projection of the latter passes the catch-bolt and is caught between the same and the clutch-bar, that neither can turn independently of the other in either direction, but both must turn together until the clutch-bar is withdrawn from ac tion by the throwout d, as above stated. This tends to prevent any uncertain or false motions of the cranks, which if moving irregularly mightlead to loss or accident by causing the plunger and other parts to be brought down when not desired. The inclined throw-out d is formed with a square neck, t, fitted to slide vertically in a bearing, Z), secured to the outer surface of the frame, there being a rod, It, connecting said neck with the treadle-lever. Aspring, If, coiled around the rod R between the square neck and a rigid bracket, d secured to the post, tends to keep the throw-out up, so as to hold with certainty the clutch-bar within the collar and out ofthe way of the projections of the band-pulley. When the foot of the operator is pressed upon the treadle, the throw-out is drawn downward, releasing the arm a of the clutch-bar, the spring f behind which latter forcing it forward to engage the wheel, as above stated. The throw-out is of peculiar shape, being better shown in Fig. 11, there being a shoulder, f formed to squarely receive and stop the arm of the clutch-bar as it comes around from the rotation of the collar. The inclined part of the throw-out withdraws the clutclrbar before the arm reaches the shoulder, so that the impact of the arm with the shoulder results only from a remnant of inertia of the moving parts after the poweris withdrawn. A spring catchbolt, It, with a beveled head similar to the catch-bolt 0 of the clutclrcollar, is insert-ed vertically in a cavity in the head of the throw out, which operates like said catch 0 in holding the arm of the clutch-bar after it passes the catelrbolt h and meets the shoulder f of the throwout, as stated. The catch springs downward and allows the arm to pass over it, when it immediately rises to its normal position and holds the arm between it and the shoulder. This prevents any backlash or rebound of the parts, and prevents the cranks from over-balancing backward or moving away from a vertical position by their own weight.

The devices for confining the projections of the wheel and arm of the cl utch'bar are inn portant, for they cause the plunger and lifters for the funnel to be steadily held or regularly moved, as the case may be, giving the opera 'tor opportunity to place the fun nel,fillcd with tobacco, in place under the plunger. These plunger-sused with this machine are made of different diameters and forms of crosssection, and funnels are supplied having their parallel or tubular parts shaped and sized accordingly, to form packages of different sizes, shapes, and weights. A pin, 9, Fig. 13, is inserted horizontally in a cavity inthe part 0 of the lifter in position to bear against the edge of the hook at. Beyond the inner end of the pin, at the bottom of the cavity, there is placed a spiral spring, 92?, bearing against the end of the pin, which causes the latter to press with some little force against the hook. These pins serve to hold the hooks in positions to catch the bead of the funnel with certainty The tendency of these pins is to force the lower ends of the hooks toward each other; but excessive motion of the hooks in that direction is prevented by the latter coming in contact with the parts 0 at the points 3 above the pins. By means of these pins and the stops at s the hooks, after they leave the deflectors 1', are held in position to encounter the head of the funnel upon their curved surfaces P as shown, which inat each operation.

ICC

sures their catching the head with certainty. A guide or rest, a", for the lower end of the funnel,is provided, being attached to a bracket or holder, 0", secured to the table 0. This rest is preferably bifurcated and placed upon the table in position to receive the lower end of a funnel between its branches, as shown in Figs. 7 and 14, these funnels being round, oval, square, or other forms of cross-section. The rest is slotted at if, and held to the supports 0 by a thumb-screw, 6 by means of which screw and slot the rest may be adjusted forward or backward to accommodate funnels of different diameters or shapes, or swung to either side out-of the way should necessity require it. It is necessary to have the lower end of the funnel,\vheu placed to receive the plunger, directly under the end of the latter, so that the plunger may pass straight down the caliber of the funnel without cramping therein. This is effected by placing the end of thefunncl within the forks of the rest, as stated.

In using this machine a plunger and several funnels of the desired shape and size are selected, and bags of a proper capacity provided. A bag is drawn over the small end of the funnel, and a quantity of tobacco, determined by weight, placed therein by an assistant-,who lightly rams it with a stick made for the purpose, so that the tobacco shall all be held in the tubular part of the funnel. The operator then places the funnel vertically under the uplifted plunger, as shown on Sheet 1, the lower end of the funnel,with the bag stretched thereon, being placed fairly upon the surface of the table in the angle of the guide-pieces a as shown in Fig. '7. The foot of the operator is then pressed upon the treadle to release the clutch-bolt,which is immediately encountered by one of the projections of the pulley-hub, and carried through one complete revolution, which presses the tobacco into a close firm block at the lower end of the tube of the funnel, and then pushes it out thereof into the bag, all the parts of the machine coming to rest at the points from which they started.

This machine is mainly used in packing smoking-tobacco. The-square neck. tof the throwout prevents the latter turning or twisting in its bearing 1), on account of the action of the arm u of the clutch-bar. The catch h is held upward bya spring, p, beneath it, and it is prevented from turning in its bearing by being flattened at one side at 0, a pin, r, be-.

ing placed transversely in the head of the throw-out, so as to bear against said flattened surface 0.
